A focused population profile of Extremadurans, their western Iberian background, closest modern genetic matches, ancestry model, and World Genetics G25 heatmap.
Extremadurans are people from Extremadura in western Spain, a region bordering Portugal and including areas such as Badajoz, Caceres, Merida, and the Guadiana and Tagus basins. Extremaduran history is tied to Roman Lusitania, medieval frontier zones, Castilian expansion, rural pastoral life, and migration to the Americas.
Spanish is the main language, with local Extremaduran speech traditions and Portuguese-border influences in some areas. Extremadura's position between Portugal, Castile, Andalusia, and western Iberia is visible in its closest genetic comparisons.
As a genetic reference, Spanish Extremadura Extremaduran is useful for comparison with Portuguese, Andalusian, Galician, Azorean Portuguese, Murcian, Castile and Leon, Castilla-La Mancha, and Valencian Alicante references.
In the World Genetics modern G25 comparison, the closest non-self match for Spanish Extremadura (Extremaduran) is Portuguese. Other nearby references include Spanish Andalusia (Andalusian), Spanish Galicia (Galician), Portuguese Azores, and Hispano-Cuban. This gives the Spanish Extremadura (Extremaduran) profile its nearest modern genetic context inside the current reference database.

The ancestry breakdown gives deeper component proportions, while closest matches show modern similarity. Extremaduran is best interpreted as a western Iberian profile with strong Portuguese, Andalusian, Galician, Castilian, and Murcian context.
The heatmap should emphasize Extremadura, Portugal, western Spain, Galicia, Castile and Leon, Andalusia, Murcia, and nearby Iberian regions.
The closest non-self match in this World Genetics comparison is Portuguese. Other nearby references include Spanish Andalusia (Andalusian), Spanish Galicia (Galician), Portuguese Azores, and Hispano-Cuban.
In the current modern G25 reference set, Portuguese is the closest listed match to the Spanish Extremadura (Extremaduran) average after removing Spanish Extremadura (Extremaduran) itself from the table.
The heatmap shows where modern reference populations are closer or farther from the Spanish Extremadura (Extremaduran) G25 average, giving the closest-match results a geographic view.
